Abstract
A smoke detector device for signalling a smoke detection in a space in an aircraft such as a cabin, a toilet, or a cargo hold of an aircraft, is mounted in a recessed position in a hole in a wall or ceiling of the aircraft. The device has at least one smoke detector enclosed in a housing (3) that also holds a smoke guide ring forming a funnel collar (7) for guiding smoke from a smoke collecting entrance (9) into a detector inlet opening (11) facing toward the space. The funnel collar (7) has a bottom (10) extending essentially on one level with the smoke inlet opening (11) of the smoke detector. The funnel collar tapers from the smoke collecting entrance (9) of the smoke guide rim to the smoke detector inlet opening (11) to form a smoke trap wherein a smoke stream toward the smoke detector is guided and accelerated. The smoke guide rim itself may function as a mounting for one or more smoke detectors, whereby a separate housing is obviated.
